The results showed that 1 transport of Gly-Pro was slightly quicker when Na+ replaced by K+ during the first period of 20 min;2 Na+ concentration gradient stimulated 4.6-fold of L-alanine transport, but had no effect on transport of Gly-Pro. Harmaline reduced transoport of L-alanine significantly but had no effect on Gly-Pro transport.

结果表明：(1)用K+替代Na+，并没有降低Gly-Pro在BBMV中的转运量，在孵育前20 min时间内，Gly-Pro的转运量稍稍提高；(2)Na+可使BBMV对L-丙氨酸的转运量提高到4.6倍，但不影响Gly-Pro的转运；二氢骆驼蓬碱显著地降低L-丙氨酸的转运，但对Gly-Pro的转运无影响。
